Is it possible to make Particles follow Displacement Node?
This is a method that i used with true displacement in experimetnal 2.79

1)Use the node wrangler addon to preview the output of the displacement node

2)the values will most likeley be clamped, so you will have to normalize them in order to see the [0-1] range. Use greater then and less then operations to find what are the maximum and minumum values

3)Use add and divide operations using the values you got in 2) to get normalized map

4)Bake the height map (I used diffuse shader and baked colour)

5)Plug the baked height map into the displacement modifier
